This design is common in many Chrysler and Dodge vehicles, including the Chrysler 300 and Dodge Charger. The rotor measures 13.780 inches in outside diameter, providing ample surface area for effective braking. Its nominal thickness of 1.102 inches ensures structural integrity and heat resistance, while the discard thickness of 1.024 inches indicates the minimum safe thickness before replacement is necessary. The overall height of 2.677 inches accommodates the rotor’s vented structure, which helps dissipate heat during braking to reduce fade and maintain consistent performance.\u003c\/p\u003e\u003cp\u003eThe rotor features five mounting bolt holes with a diameter of 0.654 inches arranged on a 4.528-inch bolt circle diameter, compatible with the specified vehicle models. The center hole diameter of 2.859 inches ensures proper fitment on the hub assembly. This rotor is designed to work with vehicles that require a 5-lug stud pattern, such as the Dodge Magnum and Dodge Challenger.\u003c\/p\u003e\u003ch2\u003eR-Line Product Line Information\u003c\/h2\u003e\u003cp\u003eThe Raybestos R-Line product line focuses on delivering reliable, OE-quality brake components suitable for a range of domestic vehicles.
